Finally I caught some decent video of my large NPW21 rigged for depower.
Here I am flying on a limp sock day and I still was able to go from no pull to enough power to scud!
Nose collapse occurs due to low wind and full depower. If you know NPWs, you'll know this is actually good nose behaviour as it resolves itself.
I've been lucky to work with the master, BigE on these kites and if you like single skins, these NPW21s are going to shake up the NPW world.
I am flying on custom pulley handles that decrease bar pressure. Will post a pic later
